Deputies met with officials at the school Friday morning and were interviewing the children, he said. Sources said the students who reported the armed woman are 6-year-old first-graders.

The private, Catholic K-12 school, in a residential neighborhood west of Rancho Santa Fe Road, was closed Friday as a precaution, Principal Michael Dominguez said.

“We had a report of suspicious activity in the area and we couldn’t verify it, so we decided to take the day off to review our procedures,” Dominguez said.

An email was sent to St. Joseph’s Academy families Thursday night informing them of the closure. The school will be open as normal Monday. The email said the school was closed “due to a potential safety issue.”
